SPECIFICATION forming part of Letters Patent No. 617,939, dated January17, 1899 1."

' Application filed 00mm '1,

To all whom it may concern.-

Be it known that I, FRANK ROBERTS, a citizen of the United States,residing at Belle Plaine, in the county of Benton and State of Iowa,have invented new and useful Improvements in Pneumatic Straw-Stackers,of which the following is a specification.

rent or blast of air.

My invention relates to pneumatic strawstackers by which the straw froma threshing or other machine is stacked or piled by a cur- As is wellknown to those skilled in the art to which my invention pertains, it isvery difficult to put a solid top on the stack or pile owing to theliability of the straw being blown over the back or rear side of thestack. I My invention is designed to obviate the above and otherobjections'and provide an attachment for pneumatic straw stackers whichshall possess superior advantages'with respect to eflieiency in use.

The invention consists in the novel construction and combination ofparts hereinafter fully described and claimed.

In the accompanying drawihgsFigure 1 is a side elevation of a pneumaticstraw-stacker with my improvements applied thereto. Fig.

2 is a plan view of the same. Fig. 3 is a longitudinal sectional View.

In the said drawings the reference-numeral 1 designates the pneumatictube of a strawstacker of any ordinary or suitable construction and isconnected with a threshing-machine, as usual. At the rear end of thistube is a pivoted hood 2, provided with arope 3,

.by which it may be controlled or adjusted.

Near. the rear end of said tube are two diametrically opposite pivots orstuds 6, which pass through slots 4 in adjustable arms 5. These studsare provided with nuts or washers 6.

The numeral 7 designates a bar secured-to said arms by means of rods 8and is provided with a rope 9. The rear ends of said slotted arms areconnected together by a plate 10, to which is hinged a deflector orplate 12, preferably made of sheet metal and provided with an arm 13, towhich is secured a rope 1*, by

which the inclination of the deflector or plate is adjusted as required.The free edges of said deflector or plate are bent downwardly;

so as to properly direct the straw to the'st'ack or pile. Connected withsaid deflector and the connecting-plate 10 is a coiled spring 15, whichholds the deflector in position.

The operation will be readily understood. v

As the straw emerges from the outer end of the air-tube it will beforced by the blast against the deflector, from whence it will fall 1.In a pneumatic straw-stacker, the comarms pivoted to the outer end ofsaid tube and adapted to be adjusted longitudinally of the same, and thedeflector hinged to the outer ends of said arms, substantially asdescribed.

2. In a'pneumatic straw-stacker, the combination withthe tube, of thepivoted hood, the adjustable arms pivoted to said tube and thespring-actuated deflector hinged to said arms, substantially asdescribed.

3. The combination with the pneumatic tube and the pivots or studssecured thereto, of the slotted arms through which said pivots pass, andthe hinged deflector or plate, sub stantially as described.

4. The combination with the pneumatic tube and the pivots or studssecured thereto,

'bination with the pneumatic tube,'. of theof the slotted arms throughwhich said pivots pass, the bar connected therewith, the plate at therear-ends of said arms, the deflector hinged thereto having its freeedges bent downwardly, and the coiled spring, substantially asdescribed.

In testimony whereof I have hereunto set .my hand in presence of twosubscribing wit A. F. BELL.
